The disclosure relates to an absorbent core capable of absorbing discharged aqueous body fluids. The core contains a swellable fluid storage material that forms, upon contact with aqueous body fluids, a fluid acquisition zone. The fluid acquisition zone is located remote from the user, to avoid flowback or rewetting of the topsheet of an article containing the core. The disclosure further relates to an absorbent article useful for absorbing discharged aqueous body fluids that comprises: A) a fluid pervious topsheet; B) a backsheet; and C) an absorbent core, as described above, positioned between the topsheet and the backsheet.

L'invention concerne une partie centrale absorbante capable d'absorber des fluides biologiques aqueux qui y sont rejetés. Cette partie centrale contient un matériau gonflable de stockage de fluides qui forme, en présence de fluides aqueux, une zone d'acquisition de fluides. Cette zone d'acquisition de fluides est placée loin de l'utilisateur, pour éviter un reflux ou empêcher que la couche supérieure d'un article contenant la partie centrale ne se mouille à nouveau. L'invention se rapporte en outre à un article absorbant servant à absorber des fluides biologiques aqueux rejetés, qui comprend: A) une couche perméable aux fluides; B) une couche inférieure; et C) une partie centrale absorbante, telle qu'elle est décrite ci-dessus, placée entre la couche supérieure et la couche inférieure.
